JUDICIAL NOTICE OF ADJUDICATIVE FACTS

(a) Scope of Rule. This rule governs only judicial notice of adjudicative facts.

(b) Kinds of Facts. A judicially noticed fact must be one not subject to reasonable dispute
in that it is either (1) generally known within the territorial jurisdiction of the trial court or
(2) capable of accurate and ready determination by resort to sources whose accuracy cannot
reasonably be questioned.

(c) When Discretionary. A court may take judicial notice, whether requested or not.

(d) When Mandatory. A court shall take judicial notice if requested by a party and
supplied with the necessary information.

(e) Opportunity To Be Heard. A party is entitled upon timely request to an opportunity to
be heard as to the propriety of taking judicial notice and the tenor of the matter noticed. In the
absence of prior notification, the request may be made after judicial notice has been taken.
